- To all whom t may concertar Y y i BQ it known that LC. `lSLEAKIN, of West Philadelphia, in the `county of Philadelphia andfStateof Pennsylvania, have invented a newvqand useful Improvement in Railroad- Tracks; :and I dofhereby declare that the following is` afull, clear, and exact description of the same, reference being had to the accompanying drawings, `forming part of this specification, fin fvvhi'cheev Y With my :improvement applied, and, Fig. 2, a planof the same. 1 "l i f responding partfsinlboth Qfigures. l i l y The grooves of thei"groovedrails` now commonly used for rail.- roads passing filled with dirttwhich is not" unfrequently the cause of the cars getting off the tracks.

`This invention consistsin 4the application i Within l the i. groove ofiindia-rubber, or some i other elastic material that vvill yield to the street getting intothe groove, or preventing anyremaimng therein that mayhave` been' fforcedin by thevvheels of vehicles running U through the` streets.

` A, is the railvvhichfis,"` or may be ofthe usual form for igrooyed rails.

I :Specification of Lettersv Patent No. 12,505, dated March 13, 1855.

' 'the level ofk theface of the rail. A single strip ofthe required Width and depth, or two "or more strips may be used. This filling of india-rubber Will be compressed by thefvveight of the cars, as the flanges -of the f Wheels pass over it, and Will allow the treads ural position.

Insteadofmdia-rubber, any other elastic filling may be used'. It may be practicable to employsteel springs in the grooves, and some flexible covering that Will be raised by the said springs to the level of the faces of thefrails, and therefore though I prefer to employ india-rubber, my invention is not limited to the employment of that material, but embraces any' elastic filling for the groove.

By thus filling the grooves, the rails may be laid flush With the streets; and thus offer groove which is formed in the track to receive the flanges of the Wheels, substantially as, and for the purposes herein set forth.
